Message information: BNLS_UPGRADECHALLENGE (0x07)


Message ID: 0x07
Message Name: BNLS_UPGRADECHALLENGE
Direction: Client -> Server (Sent)
Format:
Help

Hint: Field names highlighted in blue will display a definition if you hover over the text.
(STRING) 	 Account name.
(STRING) 	 Account old password.
(STRING) 	 Account new password. (May be identical to old password but still must be provided.)
Remarks: This message will give you data you need for SID_AUTH_ACCOUNTUPGRADE (0x57).
This message is used to upgrade an existing account from Old Logon System to New Logon System.
You must send this before you can send BNLS_UPGRADEPROOF (0x08).

Important: You must send BNLS_LOGONCHALLENGE (0x02) or BNLS_CHANGECHALLENGE (0x05) before sending this. Otherwise, the results are meaningless.

Note: Since Old Logon System and New Logon System are incompatible, you can change the password and upgrade the account at the same time.
This is not required - the old password and the new password may be identical for this message.
